Atkins/Paleo/VLC Diets in AMD, DES, and other Eye Conditions

David Langford, O.D. on September 10th, 2012 under Optoblog, Reviews •  Comments Off on Atkins/Paleo/VLC Diets in AMD, DES, and other Eye Conditions

I would like to propose that someone perform a series of studies regarding living a low carbohydrate/high fat diet and its effect on inflammation-related eye disease.

I read The Art and Science of Low Carbohydrate Living: An Expert Guide to Making the Life-Saving Benefits of Carbohydrate Restriction Sustainable and Enjoyable by Drs. Stephen Phinney and Jeff Volek. An interesting conclusion is how our bodies become carbohydrate intolerant as we age, which pushes many people into metabolic syndrome, diabetes, and hyperlipidemia. It turns out that carbohydrates, by taxing our insulin response, cause inflammation.

Hence, the American Heart Association’s war on fatty food is misguided (see Good Calories, Bad Calories by Gary Taubes) because dietary fat is only bad in the presence of too much carb intake.  While there are some high omega-6 oils which increase inflammation, it is easy for people on Very Low Carbohydrate (VLC) diets to intake the good fats like olive oil, canola oil, high-oleic safflower oil, butter, animal fats, and coconut oil. In VLC diets, your daily Caloric intake is approximately 80% fat, 15% protein, and 5% carbohydrate.

Recent research, CE lectures, and trade articles have been advising us to tell our patients to increase their omega-3 fatty acid intake via Fish/Flaxseed oil pills.  With the latest research coming from Dr. Phinney et al, wouldn’t it be more responsible to educate them regarding the New Atkins/Paleo/VLC diets?

VLC diets are already proven to tighten diabetes control which we know decreases incidence of diabetic retinopathy. Logic tells me that Atkins/Paleo/VLC will soon be proven to reduce incidence and/or severity of macular degeneration, dry eye syndrome, and any eye condition related to inflammation.

So, anybody want to do some studies?

I’d start by visiting this helpful website and reading these books:

DISCLOSURES:

Dr. David Langford before-after 50 weight loss (6'0"- 221 to 170)

With all the lost weight, I have the energy to carry other things! 😉

In 2010 I lost 35-45 pounds using the hCG diet, but could never keep off the last 10 lbs, so in 2012 I switched to the New Atkins. Now I easily maintain a 50 lb weight loss (221 to 170), and my body doesn’t even crave things like pizza and popcorn.
Also, if you click on the links above and actually buy a book, I get a tiny referral bonus from Amazon.

Free Speech in Your Practice?

David Langford, O.D. on September 5th, 2012 under Asides, op-ed, Optoblog •  Comments Off on Free Speech in Your Practice?

A urologist posted a sign at his office, and some people are going nuts.

Obama voters not wanted as clients.

Obama voters not wanted as clients.

So…I’m not sure I would pick that fight because I just want money in exchange for services, but if I felt that a certain person or entity were actively fighting against me obtaining patient volume and deserved fees, then yes, I would have to push back.

This doctor also put some literature in his waiting room about the negative effects of Obamacare and its timetable. Holy cow, imagine the left’s vitriol if you stuck a Bible in your waiting room! I put NRA magazines in my waiting area, and guys love them! I also put National Geographic in there too. You know, just to keep it balanced. I think it’s the doctor’s right to put any decent reading material he wants in the waiting room. No one is forcing them to read it. They can take their business somewhere else if they want.

I’ll bet 80% of my patients don’t even know what magazines I have in my waiting area since I don’t like to keep people waiting.

I’m still participating in Medicaid until it doesn’t make it worth my while. I don’t really agree that there is such a thing as government sponsored-medicaid, but for now I think of it as getting my own tax dollars back.

Anyway, I reserve the right to express my political, economic, and religious views to anyone who will listen, inside or outside the clinic. Just because I’m a doctor doesn’t mean I can’t be active in causes I believe in. However, I don’t think people pay me to preach to them. I’m pretty sure they came in for an eye exam. Plus I don’t have time to go off on political or religious rabbit trails because I hope the next patient is almost done with their paper work.

I don’t care what a patient’s political/religious/etc philosophy is. I don’t care if I have to speak to them in English or Spanish or through a family member interpreting, I just want a fee in exchange for a service, and I want to perform as many exams per day as possible.

@optotrician: The Phantom Menace

David Langford, O.D. on August 31st, 2012 under @ the Optotrician, Optoblog •  Comments Off on @optotrician: The Phantom Menace

Older female to college-age male: “You are a menace to society. You need to get married.” (I think she was quoting Brigham Young, but it turns out no one can substantiate that quote.)

Loud Lady at Flu Shot table: “No, I can’t take flu shot, but she nayd tetanus and diphtheria. Is thayt included in the flu shot?” (It turns out the flu shot nurse also does other vaccines.)

@optotrician Stop Sweating So Much

David Langford, O.D. on August 30th, 2012 under @ the Optotrician, Optoblog •  Comments Off on @optotrician Stop Sweating So Much

Is there anything I can do to not get that gunk buildup by the nose pads?
An ultrasonic cleaner will take out the gunk. To help it not build up, try cleaning your glasses daily under the sink with dish soap that doesn’t contain lemon.

Yesterday I didn’t have to bill a single insurance. I love no insurance days.

New phones chirp like the phones in IHS used to. They also chirp louder and more frequently if no one picks them up quickly.

Lately people are confusing the non-contact tonometer with dilation. “Okay, I’m going to put some drops in your eyes to dilate them.”
Didn’t we already do that with the puff of air?
“No, that was just an eye pressure measurement.” (I already explained that when doing it, BTW.)

AlwaysCare website is down, probably due to hurricane Isaac since the call center is apparently in Baton Rouge. Earlier in the day, the website just timed out. Later it has this message: “AlwaysAssist website is currently having technical difficulties.. Please check back later to access any information. Thank you for your patience. For immediate assistance, please call [toll-free and local numbers] in Baton Rouge. ”

Of course all circuits are busy when you try to call that number. I think it’s ridiculous that they don’t have redundant servers across the country available. I guess these hurricanes inconvenience everybody…

New Topic Category: @ the Optotrician

David Langford, O.D. on August 24th, 2012 under @ the Optotrician, Optoblog •  Comments Off on New Topic Category: @ the Optotrician

Optoblog revolutionized optometric blogging with eye doctor-related comics and poetry. Now we have “@ the Optotrician” which contains quick anecdotes and conversations that actually occur at a vision-center/eye-clinic/optical/eye-doctor-office.

This is à la Love the Liberry blog that I discovered when it was linked to by Mental Floss the other day. It’s so awesome that I’ve already read the archives back to 2007.

By the way, if you would like to be a contributor to optoblog, please see this page.

Without further delay, here is the inaugural post of @ the Optotrician:

Teenage Girl: Hey does anyone have a dime? Do you have a dime?

An asian male (from Asia), 20s, doesn’t want the full glasses power I found written in his Rx. He wants less so his eyes don’t get worse. I explain it’s debatable whether that would help, hurt, or make no difference for his future glasses magnitude, but he insists. I am fine with it as long as he is legal to drive. I show him a +0.75 shift, and he is satisfied with that.

What’s the deal with optometrists in India not prescribing cylinder? I’ve seen several Indians (from India) that have 0.75 diopters or more of astigmatism, and their glasses from last year are spherical.

Guy in 20s: Can I charge my phone here?

Man walks right past sign posting prices of eye exam. Asks optician, “How much is an eye exam?” This happens thousands of times a day.

Friendly Reminder that Utah Expiration Dates are Two Years

David Langford, O.D. on July 26th, 2012 under Optoblog •  3 Comments

When I went to renew my Utah optometrist license, I was greeted with this pop up:

Utah DOPL two year contact lens expiration reminder

Utah DOPL two year contact lens expiration reminder


Since my photo is grainy, it says,

“Under Utah law a contact lens prescription expiration date shall be two years from the commencement date unless documented medical reasons require otherwise.”

Here is the excerpt from the Utah Code regarding “Contact lens prescription”:

58-16a-102. Definitions.
(3)
(b) A prescription may include:
(i) a limit on the quantity of lenses that may be ordered under the prescription if required for medical reasons documented in the patient’s files; and
(ii) the expiration date of the prescription, which shall be two years from the commencement date, unless documented medical reasons require otherwise.

I would say it is pretty standard practice to make youth Rx’s one year, but my advice to other Utah eye doctors would be to make sure you have a check box in your chart documenting how the youth’s Rx is still changing which requires yearly monitoring, history of eye infections and need to yearly monitor eye health, etc.

I am not exactly sure when this law came into effect, but I have known about it since 2006 after I moved to Utah. From intermittent observation of outside Rx’s brought in to my vision center or patients coming in for an exam, I would say about half of the area eye doctors know about this law. Either ignorance or they document every little thing as an excuse to yearly monitor contacts. I don’t want to slight The Vision Council’s campaign of “Check Yearly. See Clearly.” but the law is the law.

What would you say is sufficient medical reason to change an adult’s contact lens Rx to less than two years?

  1. Seasonal allergic conjunctivitis? What would you change before two years after recommending Pataday/Alaway, ClearCare, and daily disposable during the worst weeks?
  2. Contact lens-related dryness? What would you change before two years after recommending Oasys/Biofinty and ClearCare/Optifree PureMoist and Refresh Contacts?
  3. Mild corneal neovascularization? What would you change before two years after recommending a silicone-hydrogel, adhere to manufacturer replacement schedule, and no overnight wear?

I would be careful because if you get too knit-picky, your patients will go elsewhere for exams.

Here is most of the audio for the 2012 Cache County Utah GOP Convention held at Mt. Logan Middle School in Logan, UT on 4-11-2012 from 6:00 PM to 10:00 PM. I neglected to “start the tape” for the county candidates, but I got the rest. I’ve broken the audio up into two files. Here is a list of the candidates and their corresponding time slots on each audio portion.

Part 1: 2012 Cache County Utah GOP Convention Audio Part 1

  • Senate Race:
    • William J. Lawrence 0:00-4:42
    • Jeremy Friedbaum 4:57-10:04
    • Dale Ash 10:11-15:20
    • Timothy Aalders 15:26-20:26
    • Orrin Hatch 20:32-25:15

  • National Committeeman
    • Don Guymon 50:06-53:00
    • Bruce Hough 53:08-56:18

Almost every candidate felt the need to relate their connection to Cache Valley. My vote for the funniest pander of the night goes to Lane Ronnow (listen to it on Part 2 0:58):

You know, everyone tries to tie themselves to where ever we are speaking, and I want you to know that, uh, in my misspent youth when I was a television news reporter I dated the dairy princess from Cache County.

Also, don’t miss Orrin Hatch’s joke at 20:51. LANGUAGE WARNING!!! 😉

Utah HB408 Swept Away for 2012

David Langford, O.D. on February 22nd, 2012 under Optoblog •  1 Comment

The UOA used a little 409 on HB408.

The UOA used a little 409 on HB408.

The Utah Optometric Association reported in an e-mail to its members on Friday Feb. 17, 2012 that the UOA’s lobbyist has word from Rep. Hughes that he will not run HB408.

Of course, they state that they have no guarantee someone won’t try to run it in a future year, so they suggest donating to the UOA-PAC.

As of today, the official Utah.gov site for HB408 doesn’t have any status updates since Feb. 4, 2012, but if lobbyists and politicians are to be believed, we can give a little sigh of relief.

“Use of Optical Scan Machines” H.B. 408 Utah State Legislature 2012

David Langford, O.D. on February 9th, 2012 under Optoblog •  12 Comments

SpecBox

SpecBox Coming Soon?

The Utah Optometric Association is very worried about H.B. 408 which is being introduced for the 2012 legislative session. I know they must be worried because a volunteer optometrist from the association called me, and I’m not even a member of the UOA.

It turns out they are rightfully worried because while the title, “Use of Optical Scan Machines,” might seem innocuous, what is really behind the curtain is pernicious.

While there is currently no text on the le.utah.gov website for H.B. 408, sources say that the bill’s sponsor, Greg Hughes, from Draper, UT (home of 1800Contacts) intends to allow the current prescription law to be changed to allow a person to buy glasses based on the reading of an autorefractor.

Apparently, the plan is for a company, like 1800Contacts, to set up a Glasses Kiosk in a popular store, like Walmart. (By the way, 1800Contacts has been selling glasses for a while.) The person puts their head in the machine, the autorefractor spits out some glasses numbers, a pupilometer measures a p.d., the person selects their frame and lens options, then they slide their credit card and wait for their glasses to arrive in the mail. (Maybe a nicer kiosk would measure the Rx in your current glasses and have you look at an eye chart, and factor those measurements into the numbers the kiosk “prescribes” you.)

If allowed, I predict an unintended consequence will be that no optical will adjust your glasses for free, like they currently do. You will have to show a receipt just to get your glasses adjusted, so everyone buying glasses from kiosks or internet sites will walk around looking like goobers and in pain from poorly adjusted glasses.

Other obvious consequences will be that people will walk around with headaches and blurry vision since autorefractors are notoriously inaccurate and will usually over-estimate nearsightedness and underestimate farsightedness. And say nothing of the fact that many people need prism to see straight/avoid headaches.

But here is the biggest reason to forsake this bill: People need eye exams to ensure good eye health. A refraction is only one piece of a complete eye exam. I’ve already written about the woman who only wanted more contacts, but because she had an eye exam, I saw some worrisome findings and referred her for more specialty care which discovered a brain tumor.

That’s just one patient. I’ve actually done that a couple times with brain tumors. Other times I’ve had patients whom I’ve diagnosed leukemia, diabetes, pituitary adenoma, increased cerebral spinal fluid pressure, glaucoma, macular degeneration, eye infections, allergy eyes, and more all just from a “routine eye exam.” None of these people thought there was something wrong- they just wanted new glasses or more contacts.

We can’t ignore that an eye exam is more than just looking at an eye chart and getting a refractive prescription.

But let’s say you wanted to. Let’s say you are simply a consumer advocate who wants to help people buy glasses. Your idea is to waste everyone’s time and money by making a law to separate the refraction from an eye exam. The consumer who values their eye health will simply also get an eye exam in addition to buying a glasses Rx and purchasing spectacles from a kiosk.

Okay, Utah Legislature, why are you stopping there? What if I’m a business that wants to sell antibiotics cheaper, to more people, than the present system of physicians and pharmacies? I want to set up kiosks that take your temperature. If you have a high temperature, you get vended an antibiotic. Sounds great for consumers, right? Why should eye care providers and opticals be the only ones to suffer? Make physicians and pharmacies suffer as well!

If you want to change the system, change it fairly for everyone. Let’s be just like third world countries which don’t require doctor prescriptions at pharmacies or optical shops. If it’s about consumer advocacy, what could be better, right?

Of course, you will essentially be forcing a large portion of health care providers to change professions. And don’t even mention how news reports will be full of people self treating, taking the wrong medicine for the wrong diagnosis, and dying. It’s a small price to pay for consumer choice, but since I have some libertarian leanings, I wouldn’t mind trying it out as long as every medical profession participates and not just optometrists.

However, if you don’t think that all roads should be toll roads and marijuana should be legal, then let’s continue to require prescriptions for medicines and medical devices, like glasses and contacts.

Choose one, Utah Legislature. Just be consistent across all professions to make the playing field level.

If you have an opinion on 2012’s H.B. 408, then contact your Utah lawmaker.

On a side note, I hope the sponsor of H.B. 408, Greg Hughes, is happy with himself. The UOA is burning tens of thousands of dollars (that it can’t afford) on lobbyists that only work for six weeks to fight H.B. 408. Even if HB408 is defeated this year, who knows if it will come up again next year and they’ll have to spend more money again! Mr Hughes, I’m not sure how you can sleep at night. You are causing poor optometrists to spend tons of money fighting legislation that you introduced only because a big business told you to. Even if you said you were sorry and withdraw the bill, you can’t un-burn the cash you’ve caused to be burned.
Please, lawmakers, try to think outside your wallet when making decisions about bills to consider during legislative sessions. I propose we only allow you to meet every two years in order to provide more stability for us business owners.

Humphrey Acuitus 5015 takes 40 minutes to warm up!

David Langford, O.D. on December 2nd, 2011 under Optoblog, Reviews •  5 Comments

The Humphrey Acuitus 5015 autoRfx/AukoK has been the most accurate autoRfx that I’ve worked with, but for a while, it’s been taking 20-30 minutes to warm up. No big deal because I get to work 20 minutes early anyway; however, for the last week it’s been taking 40-45 minutes to warm up!

I read that Humphrey stopped supporting it in 2009. Does anyone know why it would take an autorefractor 45 minutes before it stops snowing on the viewfinder video and allows you to begin using it?
